I think you answered your own question. By the time the current has
traveled from the battery, through the firewall, through the ignition
switch, through the neutral safety switch, and finally to the starter, it
has lost so much current, there's just not quite enough left. Heavier gauge
wire might help, but the weak link could still be the ignition switch, the
neutral safety switch, or any connections along the way.
If you look at the diagram, you only have about an inch of wire needed to
power the solenoid, instead of maybe 20 feet? and several connections and
switches.
This same theory can be applied to the headlights. You can use continuous
duty relays to direct power straight from the battery to the headlights.
You'd be surprised how much brighter your headlights will be simply because
you reduced the length of wire going to the headlights.
As for timing, that wouldn't prevent the starter from engaging. It would
just cause the starter to drag because the engine would be trying to turn
backwards.

After looking at the way the Ford relay is wired in, can someone help me
understand why that would help the hot start problem? This still uses the
stock solenoid to pass all current to the starter. The only thing I can
see is now maybe you get a full 12 volts to the "start" terminal, but
couldn't you do the same thing without the Ford solenoid by running a new
and heavier gauge wire from the ignition switch (or even a separate
"start switch")??
I thought that maybe the Ford solenoid replaced the one on the starter,
but then I realized that the stock solenoid physically shoves the starter
pinion gear into the ring gear, and thus must be energized to start the
car.
Could some of the hot start problem come from too much initial advance in
the timing?
I have experienced occasional mild hot start issues and would like to
avoid it. Just trying to sort out what works and why...
Thanks,

The problem you are describing is the reason a lot of people wire in a
Ford starter relay.
